“…Inulin content in roots (47% dw) was impressively higher than those reported by Castellino et al [ 9 ] for the same artichoke cultivar Madrigal ® (Nunhems SAS, Beaucouze, France) (12% dw) extracted by ultrasounds assisted extraction in the water at the same temperature. However, besides extraction method, pedoclimatic variables and harvesting time can show significant effects on extraction yields.…”

“…Moreover, according to Zuorro et al [ 16 ], the phenolic content is higher than other phenols source such as carrot peels, grape pomace, and spent coffee grounds. In addition, an interesting amount of inulin in artichoke roots (6–21% dw) was recently reported by Castellino et al [ 9 ].…”

“…Nevertheless, the length of the crop cycle negatively influences yields and the quality of the heads. This led artichoke growers to take an interest in the development of new seed-propagated cultivars for annual crops [ 9 , 10 , 11 ]. The world production of artichoke accounts for about 1678 Ktons, and Italy is the largest producer with 390 Ktons of artichokes in the world, followed by Egypt (324 Ktons), Spain (208 Ktons), and Perù (155 Ktons) [ 12 ].…”

“…Following a general trend towards the recycling biomass, including food waste and agro-industrial residues, several research studies have been performed in order to find new pathways for valorizing the residues of artichoke [ 26 ]. Some examples include the extraction of phenolic compounds [ 16 , 27 , 28 ], the production of biofuels [ 14 , 29 ], the recovery of enzyme peroxidase for wastewater treatment [ 30 ], and the extraction and purification of high-molecular-weight inulin [ 9 , 31 ]. In the light of our knowledge, little attention has been paid in sequential and eco-friendly processes that could convert residual artichoke biomass into a plethora of high-value compounds (phenols, inulin, etc.…”

A sequential extraction process has been designed for valorizing globe artichoke plant residues and waste (heads, leaves, stalks, and roots left in the field) by means of green extraction techniques according to a biorefinery approach. We investigated two cascading extractions based on microwave-assisted extractions (MAE) and green solvents (water and ethanol) that have been optimized for varying temperature, solvent and extraction time. In the first step, phenols were extracted with yields that ranged between 6.94 mg g−1 dw (in leaves) and 3.28 mg g−1 dw (in roots), and a phenols productivity of 175.74 kg Ha−1. In the second step, inulin was extracted with impressive yields (42% dw), higher than other conventional inulin sources, corresponding to an inulin productivity of 4883.58 kg Ha−1. The remaining residues were found to be valuable feedstocks both for bioenergy production and green manure (back to the field), closing the loop according to the Circular Economy paradigm.
